Ruled Surface

A revolving around its transverse axis forms a surface called “hyperboloid of one sheet”. A hyperboloid is a Ruled Surface.

Ruled surfaces are surfaces that for every point on the surface, there is a line on the surface passing it. Or, in other words, a surface generated by a line. If for each point on the surface there are two lines on the surface passing it, then it's called doubly-ruled surface. Hyperboloid is a doubly-ruled surface.

Ruled surfaces also include cylinder and helicoid. There are only 3 doubly ruled surfaces: • Hyperboloid of One SheetHyperbolic Paraboloid • plane.

Hyperboloid can be used for gear surface, called a Hypoid. (Source: Penrose Tiles to Trapdoor Ciphers by Martin Gardner. Buy at amazon, chapter 15).
